. ADJUSTABLE LAMP-FIXTURE. V I

To all whom it may concern."

Be it known that I, HENRY R. Hu'BEnIoH,

a citizen of the United States, residing at Cleveland, county ofCuyahoga, State of Ohio, have invented certain new and usefulImprovements in Adjustable Lamp- Fi'xtures, of which the following is aspecification. c

My invention relates to electic lamp firttures and more particularly tofixtures of this character which are provided with means for adjustingthe light source to various positions and which are especiallyserviceable for reading, shaving and other operations requiringan-adjustable lamp. I

According to my invention, I provide a standard having a slot to receivethe lamp and means whereby the lamp may be clamped in various positionsin said slot. 7

" be caused to assume-a great variety ofposifollowing detaileddescriptlon of a species tions. By means of the combination of;thesefeatures a wide range ofadjustability is obtained. My inventionfurther comprises specific improvements in the attach-- ment of the lampto the standard, and'in the attachment of the standard to the base. The

device as a whole presents an ornamental appearance and'variouslotherfeatures and advantages thereof will appear from the thereof and fromthe accompanying draw-'- in the drawing, Figure 1 is an end-'elevationofa, p'ortablelamp and support con- :stituting one exemplification" of myinvention; Fig.2 isa side elevation thereo-'show'-,

The law -showncomprises a base 10hr suitable weight tobalance the otherparts in any of the desired positions. eye 11 Specification of LettersPatent.

Application filed August 21, 1915. Serial No. $6,626.

Patented June table or similar article of furniture. Supported upon thebase 10 is an adjustable standard 12, which, as shown,'is S-shaped.

The upper and lower curved portions 13 and 14 respectively of thestandard are slotted substantially throughout, as shown at 15 and 16respectively. The slot 15 permits of the adjustment of a lamp 17'carriedin socket 18, .and, if' desired, a reflector 19 The slot 16 permits thestandard to be ad-F' justed with respect to the basal 0.

The attachment-of the standard 12 to the base 10 is, as shown,substantially the same 7 as that of the lamp socket 18 to the standard12,'e xcept that in the former case the attachment 20 is so disposedthat the member 12 is movable relatively thereto, whereas in j thelatter case the attachment 21 is so disposed that itis movablewithrespect to the standard 12; Inasmuch as the clamping portions of these"parts are substantially the same, the attachment 21 only is illustratedand is shown in Fig.3; The lamp socket 18 has at the bottom thereof aninternally threaded sleeve 22 in which engages an ex ternally threadedtubular bolt 23, thus providing 'a socket supporting means at one end ofthe said bolt." The tubular bolt 23 permitsthe' passage. of theconductors 24 leading to'the socket terminals. The said bolt pamesthrough the slot 15 in the standard 12, having aflattened portion 25engaging the said slot so as to prevent turning. The head 26 of the said[bolt engages the inner surface of thecurv'edportion 13 of the standard12. The bolt 23 also passes loosely through and carries bearing plate 27which,

as shown, is of a channel shape, the side members of which engage'theouter-surface of the portion 13. The saidsides have proj ections 28which enter the slot 15 and serve to guide and center thebearing plateas well as the bolt 23 and attached parts with re spect to, the standard12 A clamp or winged nut 29 is threaded upon the bolt 23 inter- "mediateth e'sleeve 22 and the bearing 27.

a By looseningthe clamp or winged nut 29,'the

bearingplate 27 and the parts carrying the same may be moved to anydesired position with respect to the slot 15, whereupon the clamp maybetightened, thus drawing thehead 26 of'bolt 23 against the inner surfaceof the standard 12, and the parts will be securely held. The standard 12may be readily adjusted with respect to the base 10 by loosening thelower clamp and turning the said standard with respect thereto,whereupon the clamp may be again tightened. While in Fig; 2 twopositions for the lam and standard respectively are shown; it is obviousthat these parts maybe caused to assume a great variety of positionswith respect to each other and to the base 10.

Various modifications of the device hereinbefore described will readilysuggest themselves to those skilled in the art and are to be .consideredas coming within the scope of my invention, which is set forth in thefollowing claims.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is

1. A lamp fixture comprising a standard having a slot therein, a boltpassing through the said slot and carrying at one end a lam socketsupporting means and at its other en means for engaglng the innersurface of said standard, and clamping means comprising a member carriedby said bolt and engaging the outer surface of said standard and meansfor causing said member to bear tightly against said standard or to Bereleased therefrom as desired.

2. A lamp fixture comprising a standard having a slot therein, a tubularbolt passin through said slot and having at one end thereof a lampsocket supporting means and at the other means engaging the inner,surface of the said standard, means carried by the said bolt andengaging the outer surface of said standard and means for clamping thesaid engaging means or releasing the same from' engagement with saidstandard.

3. A. lamp fixture comprising a standard havin a slot therein, abolt'passing through the said slot and having at one end thereof lampsocket supporting means and at the other a head adapted to engage theinner surface of said standard, means carried by said bolt and engagingthe outer surface of the said standard and means for clamping saidheadto said standard or releasing it therefrom as desired.

4. In a lamp fixture the combination of a standard having a slottherein, an externally threaded bplt assing through said slot and havinga hea engaging the inner surface of said standard, a bearing plateloosely carried on the said bolt and engaging the outer surface of thesaid standard, and an internally threaded member engaging a thread onsaid bolt and adapted to engage the said plate to clamp the aforesaidhead against the said standard. I

5. In a lamp fixture the combination of a standard having a slottherein, an externally threaded bolt passing through said slot andhaving a head engaging the inner surface of said standard, a bearingplate loosely carried on the said bolt and having a projection engagingthe said slot and engaging the outer surface of the said standard, andan internally threaded member engaging the thread on said bolt andadapted to be tightened against the said plate to clamp the aforesaidhead against the said standard.

6. In a lamp fixture the combination of a standard having a slottherein, an externally threaded bolt passing through said slot and havinahead engaging the inner surface of sai standard, a bearing plateloosely carried on the said bolt and engaging the outer surface of 'thesaid standard, and an internally threaded winged member engaging thethread on said bolt and adapted to be tightened against the said plateto clamp the aforesaid head against the said standard.

In witness whereof, I have hereunto set my hand this eighteenth day ofAugust, 1915) HENRYR. HUBERI H.
